ABSTRACT: "Arsenic has been recognized as a poison since ancient times. Understandably, the public may have
concerns about low levels of arsenic found in some municipal water supplies and in some private wells.

Arsenic is a natural element widely found in the earth's crust. There are trace amounts of it in all living matter. Arsenic may enter lakes, rivers or underground water naturally, when mineral deposits or rocks containing arsenic dissolve."
